Explanation:
By the law of conservation of the momentum The car-bug system moment will remain the same before and after the collision. And since the mass of the car is much higher than the bug, the change in velocity of the car will be negligible as compared to the change in velocity of the bug and hence the change in momentum of the bug will be very large and change in momentum of the car will be negligible.

Explanation:
The frictional force is too much compared to the gravitational force
Explanation:
This is because of the great amount of frictional force between the book and the wall.
Also, the force of gravity on the book is not high enough to cause motion of the book to slide downs.
Frictional force is a force that opposes motion.
- For the book to slide down, it must overcome the force of friction acting on it opposite to the direction of gravity.
- According to newton's first law 'a body will remain in its state of rest or uniform motion unless acted upon by an external force'.
- Assuming the external force is gravitational force, clearly we see that the force is less than the frictional exerted on the book by pinning it to the wall.
- This frictional force is a static friction that is on a body at rest, it must be overcome by a larger force before motion takes place.
Fr > fg
Fr is the frictional force
fg is the gravitational force
